This is a good (and only 6:30) video. It seems to support the theory that eventually the universe will more or less end, but time will continue forever. It's a total mindfuck to think of the universe and time as separate.



Edit: Holy fuck I love science!

Scientist Brian Cox has a theory that when suns explode, they become nebula and those gases over time again reform and become a different kind of sun and it goes through the same cycle, exploding again and becoming nebula and the same theory might be applied to our universe. It explodes out then retracts to an impossibly dense minuscule mass and explodes again and the whole thing starts again.

I like that theory.

I think that's my (and my wife's) favorite theory as well, but it seems that the "big crunch" and the cold chaos (or freeze out) theories are gaining more acceptance. I'm not too bothered by any of them really. I just think by the time this happens, who knows what kind of form we will have evolved into. We could just be masses of energy at that point, so the idea that the universe may be a big ball of photons may not spell our doom.

I like the religion comparisons in the video at the top of this page. Religion and science aren't really that far apart. Most people believe some kind of energy leaves the body upon death. If our bodies turn out to just be a vessel for energy, that is essentially the same as a body and a soul. And maybe "heaven" is just our energy exploring the cosmos.

It's gonna be fun as hell to see where science takes us.

If it weren't for your generally dour mindset, I would probably point something out right here regarding the likelihood that you'll be around to see any of it.

Seems like we left out "The Big Rip" in our "Ultimate Fate of the Universe" discussion. It essentially says that the universe will continue to expand until all matter is ripped apart.



And here is a nice info graphic on "The Big Bounce," which dime mentioned a few posts above.

Wow! Rep. Paul Broun (R-GA): "Evolution, embryology and the Big Bang Theory are lies straight from the pit of Hell."

Well.....I just looked it up on the internet and got the answers.

Nevermind.

these are interesting questions

As far as what's beyond the universe, that answer is probably more universes. Maybe we should start thinking of it as more of a multiverse than a universe. Most of the questions knee tunes had are related to string theory.

Here's a great (and short) video explaining string theory and multiple universes.

So that begs the question: Are there infinite multiverses? Or is there a set of universes on the outskirts of the multiverse, where "what's beyond" becomes relevant again?

It's the same on the creation of the universe question. Even if our universe was simply born from some other universe in the multiverse (or a precursor universe), where did the initial universe come from, or where did the multiverse itself come from? I think the idea of a multiverse is interesting, and it can answer questions about our universe, but it avoids answering questions about the origin of existence that are what most people are really getting at when they question the origin of the universe.

Quick disclaimer: came up with these questions before watching the video, so if they're talked about in there I haven't seen.

There is a mathematical theorem demonstrating the necessity of incomplete spacetime geodesics for universes in expansion, which ours is. This is to say that any such multiverse must have a beginning.

More universes cannot be "beyond" ours in any meaningful sense, since individual universes in mutliverse theory are causally disconnected no matter how fast, long, or far they expand (even if indefinite). As far as what's "out there" beyond the edge of the expansion of the event horizon (particle horizon) there is no way we can define "out there" because there are no events, by definition, to which we can refer. There isn't even "nothing" out there - there is no "out there."

Post subject:  Re: our universe is so rad

I think the idea of infinite multiverses is more than probable considering the nature of the theory. It's only logical to think that if our universe is forever changing and expanding, that the same can be said of the multiverse. The theory will undoubtedly comfort a lot of people who want to know that when our universe is out, not all existence is extinguished.
As far as "what's beyond" is concerned, are we sure there is a “beyond?” And if there is, maybe it's just "photon soup" left over from the Dark Era of the Big Freeze from other universes. Or is the "what's beyond" question really just our need for something greater than ourselves.
If The Big Bang is applied to the original universe in our multiverse isn't that enough of an "origin of existence?"

No, a multiverse itself must be geodesically incomplete, and thus must have a beginning; no particular universe can persist in life-giving conditions under the second law of thermodynamics.
